About
Cortinarius infractus is an edible mushroom found in hardwood forests around the world. It has a distinctive radish-like odor and initially very bitter taste that fades with cooking. This mushroom contains unique sesquiterpenes and is sold commercially in European markets after processing to reduce bitterness.

Ectomycorrhizal Cortinarius species participate in enzymatic oxidation of humus in northern forest ecosystems
In northern forests, belowground sequestration of nitrogen (N) in complex organic pools restricts nutrient availability to plants. Oxidative extracellular enzymes produced by ectomycorrhizal fungi may aid plant N acquisition by providing access to N in macromolecular complexes. We test the hypotheses that ectomycorrhizal Cortinarius species produce Mn-dependent peroxidases, and that the activity of these enzymes declines at elevated concentrations of inorganic N.
